This sounds pretty interesting. 

Also:

"A typical 15 year old. But all will change when the robbers come back to his house and kills him. He then finds out that you have to fight to the death to see who will make it back alive and who will be forever dead."

Did you mean her? I assume that was a typo, since he couldn't fight people if he was dead.

Well the robbers come back to the house after the girl is dead a kill the boy. He then finds out death is really just a battle to see who will survive a death match. So the people who survive it come back to life and live a normal life on earth. But those who loose the death match have no way of living again and are dead forever. So it's kinda like an afterlife that you fight in.

Oh okay, I understand now. That's pretty interesting.
